1.指定容器名字运行 (docker run --name)

# docker run --name dllhook -i -t -d piaoyun/ubuntu:16.04 /bin/sh
fd293c88881d4405294658d0ea11c7f1eb173726cf27e0a7b16daff01374ba7b


2.启动/停止容器 (docker start/stop/restart)

# docker start dllhook // 启动
dllhook
# docker ps
CONTAINER ID        IMAGE                  COMMAND             CREATED             STATUS              PORTS               NAMES
fd293c88881d        piaoyun/ubuntu:16.04   "/bin/sh"           4 minutes ago       Up 4 seconds                            dllhook
# docker stop dllhook // 停止
dllhook
# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES


3.外部访问容器 (docker run -p -P)

// 当使用 -P 标记时,Docker 会随机映射一个 49000~49900 的端口到内部容器开放的网络端口
# docker run -d -P training/webapp python app.py
9678e0e4500edf088f8a3fffbab28159d0456642063d5da7d55229edd24ddebf
# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                     NAMES
9678e0e4500e        training/webapp     "python app.py"     7 seconds ago       Up 7 seconds        0.0.0.0:32769->5000/tcp   stupefied_roentgen

// 当使用-p(小写)标记时,则可以指定要映射的IP和端口,但是在一个指定端口上只可以绑定一个容器
# docker run -d -p 80:5000 training/webapp python app.py
65cfabd02c7286c12249ce173a86a70c04aae8ec81e9339174c534b362593cce
# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                  NAMES
65cfabd02c72        training/webapp     "python app.py"     5 seconds ago       Up 4 seconds        0.0.0.0:80->5000/tcp   adoring_mahavira


4.保存对容器的修改 (docker commit)

Usage:    docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]

Create a new image from a container's changes

// 先在home目录下添加一个test文件夹作为测试
# docker run -t -i piaoyun/ubuntu:16.04 /bin/bash 
root@851a5cbb9dbb:/# cd /home/
root@851a5cbb9dbb:/home# mkdir test
root@851a5cbb9dbb:/home# ls -al
total 12
drwxr-xr-x  4 root root 4096 Jun 27 08:25 .
drwxr-xr-x 38 root root 4096 Jun 27 08:25 ..
drwxr-xr-x  2 root root 4096 Jun 27 08:25 test

// 另外开一个终端
# docker ps
CONTAINER ID        IMAGE                  COMMAND             CREATED             STATUS              PORTS               NAMES
851a5cbb9dbb        piaoyun/ubuntu:16.04   "/bin/bash"         2 minutes ago       Up 2 minutes                            youthful_almeida

4.删除容器 (docker rm)

# docker rm -f dllhook


4.1.删除两个id相同的镜像 (docker rmi)

#docker images
REPOSITORY                                          TAG                 IMAGE ID            CREATED             SIZE
piaoyun/centos                                      latest              6b9d49175255        About an hour ago   200MB
piaoyun/ubuntu                                      16.04               eb85479e6f47        2 hours ago         114MB
registry.cn-hongkong.aliyuncs.com/chinapyg/ubuntu   16.04               eb85479e6f47        2 hours ago         114MB

有两个 镜像ID eb85479e6f47,删除一个

# docker rmi registry.cn-hongkong.aliyuncs.com/chinapyg/ubuntu:16.04
Untagged: registry.cn-hongkong.aliyuncs.com/chinapyg/ubuntu:16.04
Untagged: registry.cn-hongkong.aliyuncs.com/chinapyg/ubuntu@sha256:14d4516c31dd4fe56e33df344cd468ad323feca13f613b45fb7a48a09205b907

再次查看:

# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
piaoyun/centos      latest              6b9d49175255        About an hour ago   200MB
piaoyun/ubuntu      16.04               eb85479e6f47        2 hours ago         114MB

4.2.删除none镜像

# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
piaoyun/ubuntu      16.04               da5d00d78d23        About a minute ago   114MB
<none>              <none>              24dda671df60        2 minutes ago        114MB
piaoyun/centos      latest              6b9d49175255        3 hours ago          200MB

// 此处有none镜像,直接删除会报错
// 按照下面步骤删除
# docker stop $(docker ps -a | grep "Exited" | awk '{print $1 }') // 停止容器
c791561c3361
d4cc476c6fc4
e1621bf62633
9f3e3bd661e2

# docker rm $(docker ps -a | grep "Exited" | awk '{print $1 }') // 删除容器
c791561c3361
d4cc476c6fc4
e1621bf62633
9f3e3bd661e2
64326e8e3531

# docker rmi $(docker images | grep "none" | awk '{print $3}') // 删除镜像
Deleted: sha256:24dda671df600d6833d5e47b9eccfebf7642c01f162c9bcbdd1259101a8a11a0
Deleted: sha256:f3ebd8e6ddf325e38a6f1af75065485ff9781555c76c8a6e0871c9d7fffcd740


5.修改TAG (docker tag)

docker tag IMAGEID(镜像id) REPOSITORY:TAG(仓库:标签)
// 例子:docker tag eb85479e6f47 registry.cn-hongkong.aliyuncs.com/chinapyg/ubuntu:16.04


6.重命名容器名(先确保已经运行) (docker rename old  new)

# docker ps
CONTAINER ID        IMAGE                  COMMAND             CREATED             STATUS              PORTS               NAMES
a04d920e986d        piaoyun/ubuntu:16.04   "/bin/sh"           13 seconds ago      Up 12 seconds                           hopeful_liskov

# docker rename hopeful_liskov piaoyun  // 修改hopeful_liskov-->piaoyun

# docker ps
CONTAINER ID        IMAGE                  COMMAND             CREATED             STATUS              PORTS               NAMES
a04d920e986d        piaoyun/ubuntu:16.04   "/bin/sh"           33 seconds ago      Up 32 seconds                           piaoyun
